VEC-202 Instruction Manual Mini Keyer with Memory

Introduction

The VEC-202 Mini Keyer with Memory is a microprocessor controlled keyer

that provides iambic key operation and dot-and-dash memory to make sending

perfect code easier. It has tunable code speed, code weight, and sidetone

frequency; it supports both direct and grid-block keying outputs. You also get to

choose between Iambic Type "A" and Type "B" keying. It even has a volatile

memory to record and play a message of your choice.

Control Functions

1. The Power button turns the unit ON and OFF. The power is ON when the

button is locked in the "in" position and OFF in the "out" position.

2. The Semi-Auto/Auto allows semi-automatic "bug" and manual operations.

The keyer generates dots automatically when a squeeze or single lever key is

used. Dashes are manually made. The keyer is completely manual when a

straight key is used. Semi-Auto is active when the switch is locked in the

"in" position and Auto is active in the "out" position.

3. The Message button lets you record and play a message from the volatile

memory. It is a momentary push-buttom that is time sensitive.

4. The Speed control varies code speed from 2 to 65 WPM. Turn the control

clockwise to increase speed and counter-clockwise to decrease speed.

5. The Volume control adjusts the sidetone level of the internal speaker. Turn

the control clockwise to increase the volume and counter-clockwise to

decrease the volume.

6. The Weight control varies the code weight. This control is located

internally. When looking at the unit's front panel, it is accessible through

the small hole on the left side, closest to the rear and may be adjusted by

inserting a small, flat-headed screwdriver. The standard dot-dash-space ratio

is 1:3:1 (trimpot at mid-range). This control is turned clockwise to increase

dot and dash lengths and counter-clockwise to decrease dot and dash

lengths. With the standard timing defined as 100% weight, the code weight

varies in the range of approximately 10% to 190%.

7. The Tone control sets the desired sidetone pitch from approximately 200 to

1000 Hz. This control is also located internally. When looking at the unit's

front panel, it is accessible through the small hole on the left side, closest to
